TYPEWRI'IING; MACHINE.

Application filed January 10,1924r'.

This invention relates to typewriting machines of the fan-fold or continuous billing type, one form of which is shown in the patent to l Vernery & Smith, No. 1,132,055, dated March 16, 1915, and more particularly to machines for typing selectively on any typing, and, after the typing on one section has been completed, the super osed plies or webs are straightened and a re..ative shifting between such web-plies and carbon-sheets efiected preparatory to using the carbon sheets with the next unused section to be typed. Usually each section typed is severed as soon as the proper association of the carbon-sheets with the next unused section of the web-plies is completed. The webplies may be entirely separate, or may be joined at their edges, as tor example, in fantolded webs, and preferably each ply has thereon a succession of like forms, the forms of the superposed web-plies being in register.

For certain classes of work, it has been found desirable to have a plurality of packs of such web-plies together with interleaved carbons so arranged inthe machine that sub stantially all that is necessary preparatory to typing on any selected pack is to insert the leading end of such pack around the bottom of the platen to the printing line; It has been proposed to arrange such packs in superposed; relation. Under such conditionspthe packs YitQIKl to the platen-frame from guiding devices at different heights,

and it is impossible to straighten certain packs beneath the platen to as great an en tent as others.

An object of the present invention is to provide controlling; means for the packs of web-plies and interleaved carbon sheets such thaih when any packis in position for use;

its path from the associated guiding deviceto the platen is substant ally the same'asfor any other of such packs whichmaybe put into use.

According); to th present embodii nent of" the invention, the separate packs ofwcb" Serial No. 685,339.

plies may be arranged side by side, and the carbon-sheets interleaved between said webplies may be controlled by carbon-carriers supported on a common frame or table which may be detachably connected at its forward end with the rear of a typewritercarriage, to permit any one of said packs to be brought into co-operative relation with theplaten, by effecting a lateral shifting of said table relatively to said carriage.

Provision may be made of means to secure said table to the carriage when any adjustment of the table relatively to the carriage has been eliected.

Other features and advantages will hereinafter appear.

Figure 6 is a: front elevation, taken along the line 66 of Figure 5, looking in the direction of the arrows.

Upon the depression of keys, not shown, type-bars 10 are swung upwardly and rearwardly to cause types 11. thereon to strike against a platen 12 mounted by means of an axle 13 in arms 14: of a platen-displacing; frame 15. saidarms being pivoted at their forward ends on a shaft 16 extend. be tween the ends 17 of a platen-frame lo, and normally resting at the rear on a shaft 19 journaled in theends 17 of the platen-frame. Mountedon theshai t 19 are hooks 9.0 to engage pins 21 projecting laterallyfroin the 14 of theplaten-displacing frame, and to' thereby hold the platen-displacing frame in its normal position, and preferably one oft' the hooks is provided with a finger piece 22 for shitting'the'hooks 20 to inettec-- tive position, to penniittheplaten to he disk lOS placed, when necessary, in the operation of the fan-fold machine, The platen-displacing frame also comprises a paper-table supported on the arms 14 of said platendisplacing frame, and having attached thereto a gage-bar 24 on which a gage 25 may be adjustably secured at any desired of a rearward extension 32 of the carriage.

which travels therewith in letter-feeding direction. The rearward extension of the carriage comprises front and rear members of rods 33 and forwardly and rearwardly extending members or rods 34, said rearward extension being guided on a rear rail 35 on a supplementary main frame 36 by means of rolls 37 engaging said rail, at the top and bottom thereof, and pivotally mounted on brackets 38 attached to certain of the forwardly and rearwardly extending rods 34.

As herein disclosed, arovision is made of three carbon-carriers 39 arranged transversely of the mac iine to run forwardly and rearwardly on rails 40 mounted on forwardly and rearwardly extending members 41 in a frame 42, which comprises additional forwardly and rearwardly extending members 41 intermediate those carrying the rails 40 and transverse members 43 at the front and rear. At each end the rearward transverse member 43 is provided with down war-dly-extending brackets 44 connected by a member or red slidable in perforations in brackets 46 extending upwardly from the ends of the rear member The front member 43 of the frame is also provided with forwardly-extending brackets 47 carrying a transverse rod 47 to enter slots 48 in ears 49 extending up *ardiy from the brackets 31, to connect the frame 42 with the typewriter-carriage 27.

In order to locate the frame 42 so as to bring the track of a selected carbon-carrier to the proper position with relation to the platen 12, the transverse rod 47 is provided with notches 50, the diameter of which is greater than the width of the slots 48, to receive the portions of the ears 49 at the rear side of the vertical slots 48. These notches 5O serve to position the carbon-carrier tracks definitely with reference to the carriage 27. Pivoted on the ears 49 are hooks or latches 51 to engage the top of said rod 47* to hold it in said slots 48 when placed therein, each of said latches being urged to forward position by a leaf-spring 52, and being provided with a pin or stop 53 to engage the corresponding ear 49 and limit the rearward movement of the latch, and with a finger-piece 54 at the upper end for use in releasing the latch; It will be seen that, upon releasing the latches 51 to permit lifting the rod 47 out of the slots 48, the frame 42 may be swung upwardly about the axis of the rod and. shifted laterally by sliding the rod 45 in the brackets 46 to bring the track of another carbon-carrier 39 into proper position with reference to the platen, to replace the carbon-carrier previously in operative position. The frame 42 may then be swung clownwardly to cause the fingers at the rear of the slots 48 to enter the corresponding notches in the rear side of the rod 4'? and to permit the latches 51 to move into effective position over said rod, and to seat theinselves in notches 55 in the front of the rod 47*. It will be seen that the notches 55 serve to determine the various positions of the frame 42 in the same manner as the pairs of notches 50. v

Each of the carbon-carriers 39 comprises a base 56 provided with grooved rolls 57 to engage the edges of the corresponding rails 4.0, and at opposite sides of each base stepped blocks 58 are provided to support carbon blades or holders 59 to which are attached the rear ends of carbon-sheets 60 interleaved between the plies 61 of packs 62 of web-plies fed from suitable sources of supply over a rear guide 63 supported in upward extensions of the brackets 44. To maintain such packs in suitable position with reference to the car bon-carriers 39, provision may be made of side gages 64 adjustable along the guide 63. When not in use, the packs )2 with their interleaved carbons are folded back over the corresponding carbon holders or blades 59, as indicated in Figure 2.

When any one of the packs 62 of webplies is to be used, the platen-displa'ing frame 15 is released by means of the finger piece 2 and the platen-displacing frame is swung upwardly and forwardly. The leading end of the selected pack of web plies together with the interleaved carbons is then drawn forwardly between suitably positioned side gages 65 on a transversc rod 66, supported at its ends in the brackets 47. and is passed beneath the platen, and, at the -delivery side of the platen, between the platen and a knife 67 associated with the platen-displacing frame 15 The platen 12 is then restored to its normal position and typing effected in the usual inannen When the typing upon one set of forms has been completed, the platen is again displaced, the leading edges of the web-plies advanced to the leading-edge gage. and the carbon-sheets retracted by means of a handle attached to the carbon-carrier 39 in .use. The platen may then be restored to normal position, the typed sections severed by the knife 67, and the operation repeated. It should be understood that the pack to be used is necesit e sarily the one associated with the carboncarrier whose track is operatively positioned with reference to the platen.

When it is desired to type on one of the other packs of web-plies, the leading end of the pack formerly in use is withdrawn from the platen and folded rearwardly over the carbon blades or holders of the corresponding carbon-carrier, as indicated in Figure 2. The latches 51 are then drawn forwardly by the linger-pieces 54: and the rod 47 lifted out of the slots lS to free the frame 4-2 from the carriage, and the frame i2 is slid transversely of the machine to a position to bring the selected carbon-carrier 39 and its track to the proper position with reference to the carriage 27. The rod 47 is then swung into the slots 48, the exact position of the frame being determined by the slots 50., which must coincide in position with the ears. the latches 51 being cammed forwardly by the rod l? in its downward movement and then released to snap back into efiective position to enter slots 55 and. by engagement with the upper side of said rod i'i' to hold it in the slots 48. The heading end of the selected pack may then be drawn forward and passed under the platen as described for the first pack selected.

In the form of the invention shown in Figures 1 to at, inclusive, the frame or extension 32 is fixed to the carriage and consequently moves to the same extent, sothat the rear rail 35, supported on the auxiliary frame, may be of moderate length The frame 42, however, is shifted with reference to the extension 32 and when, for example, the frame 42 is in one of its extreme positions, the left, as shown in Figure 4, consideralole twisting stress is exerted on the extension' 32, and the lifting of the right side of the extension 32 from the rail 35 is prevented by the lower roll 37 on the right-hand bracket, asseen in Figure 4-7. The use of rolls to engage the lower side of the rail permits asy movement of the extension with the carriage notwithstanding the twisting stress exerted. In the form of the invention shown in Figures 5 and 6, the frame or extension 32 is omitted and the carbon-carriers are mounted directly on a frame 69 similar. to the frame d2 of. the form illustrated in ures 1 to 4 but supported directly on a rear rail 70 by means of grooved rolls 71 resting on the rail 70 and pivoted inbraclzets 72 .attached to certain forwardh and rearwardlv extending members 73 of the frame 69, which also. comprises front andrear trans. verse members H To prevent the rolls from leaving the rail, the lower ends of the brackets may oe offset to engage; the lower sideof-the rail. Crertainlof the forwardly and res rwardl y extending; members have flat rails 75 thereon tozengageiin er oved rolls,

7 is L pivoted in. the bases I 5610f": the" carbons carriers 39, which may be the same as those disclosed in Figures 1 to 4:, inclusive. The frame 69 is also provided at its rear with a guide or rod (6 supported in upright brackets 76? and provided with side-edge gages 76 for the packs of web-plies as v pass from the sources of supply to the carbon ca rriers 39'. At the front the frame may be detaehably connected with. the carriage in the same manner the frame 4,; disclosed in Figures 1 to 4, and. provision. may also be made of a guide 66 correspond: ing to the guide 66 shown in Figure 2 and provided with adjustable side pages 65 in Figure 2. a i

In the form of the machine disclosed Figures 5 and 6, the extension or frame 69 may be moved not only the amount due to the travel of the carriage. but to an additional amount due to the shifting of theezrtension relatively to the carriage 27 to post tion the carbon-carriers 39 at the sides in alignment with the carriage, The rail 70 therefore ofgreater length than the rail shown in Figures 1 to 4. inclusive, and, in

order to render the rail 70 sufficiently rie'id, provision may be made of supporting brackets 72 extending laterally from the sides of the auxiliary frame 36.

Preferablyeach pack 62. when in use, is guided around the bottom of the platen and )GlZWQQTL the platen and the releasable front and rear feed-rolls 77 and 78, respectively, by a rear paper-table 79 and a paper-apron 80. Obviously, when the platen is displaced, the pack will be released. To rotate the platen for feeding the pack gripped between the platen 12 and. the feed-rolls T7 and 78, provision may be made of egears 81 on the ends of the platen-axle 13 and, when the platen is infnormal position, in alignment x ith gears 82 on theinner ends of stub-shafts journaled in the ends 17 of th carr age and having at their outer ends fin, r-wheels F4. The gears 81 andSQ at each end of the platen mesh with a broad pinion mounted on the shaft 16, so that the platen operatively connected at all times with the linger-wheels 84'. If. desired, provision may be made of line-space mechanism (not shown) to act on one of the stub-shafts.

Variations may be resorted to within the scope of the inve ion, and portions of 56 l: oth
